This paper based on the research of the different temperatures of AZ31 magnesium alloy by continuous variable cross-section direct extrusion (CVCDE) studied the effect of forming temperature on the deformation characteristics of magnesium alloy by CVCDE. It was found that the average size of grains and the proportion of large angle grain boundaries in microstructure increased obviously with the increase of forming temperature, which showed dynamic recrystallization has been relatively adequate. Because the dislocation density inside the grains was higher and the texture was weakened obviously at 623 K by compared with other temperatures, the yield strength and elongation increased at first and then decreased with the increase of temperature. This paper reveals the deformation mechanism of AZ31 magnesium alloy by CVCDE, which can provide scientific guidance for the development of magnesium alloy extrusion products with high property.
